A drier reduces the moisture content of a synthetic rubber from 24 kg water per 100 kg moisture-free rubber to 1.5kg of water per100 kg moisture-free rubber in the product. Using a basis of 100 kg/h of moisture-free rubber entering, calculate

a) the mass flow rate of product leaving kg/h

b) the mass flow rate of water evaporated kg/h

c) the rate of water removal if the feed moist rubber is supplied at 3 te/h
